Looks like they already did :)

I just installed version 2.31 of SA today, and it still doesn't trigger it
for that spam:

X-Spam-Status: No, hits=3.3 required=5.0
        tests=FROM_NAME_NO_SPACES,PLING,MONEY_BACK,PORN_14,
              DATE_IN_PAST_06_12
        version=2.31


I guess they're wording stuff more carefully now. But I think 1 spam out of
800 (samthecomputerman.com/sys) is an acceptable false negative. Of course,
I didn't tweak the settings at all...it's out-of-the-box scoring.
